From the press release: From the moment he is handed a possibility of makng the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Wales Day 7
In our final day of our Wales journey, we spent the day strolling across the beautiful countryside of Cregennan, one of several parks along the flanks of the Cadair Idris range, which runs north-south to the coast. This park is closest to the ocean, so at our highest point we were overlooking the Irish Sea and the town of Barmouth.
The three pictures on the right are only a small selection of the beauty of this region. There were several magnificent lakes nestled amid the mountains and fields. There were pastures with numerous sheep, some eating, some resting like white blobs on the green grass, and some “baa’ing” at each other. It was especially entertaining when a lamb started calling out for its mother, the mother responding, and then the two searching and finding each other.
And of course there were the standing stones and ancient ruins scattered about on several hilltops.
The abandoned house in the second picture is of special interest because it had been the home of an obscure 18th century Welsh composer by the name of John Williams. Williams was actually quite successful in his time, but only recently have some locals rediscovered unpublished manuscripts of his work. They plan a performance this fall.
Apparently his father was a hat-maker of some note, able to accumulate enough wealth to build this large country house in such a setting. Though I don’t know this, I suspect his success came from providing high quality hats to the upper classes, and this in turn gave his son the contacts necessary to become even more successful as a composer.
The last photo was taken as we walked downhill toward the ocean in a forested area beside a flowing stream, passing numerous waterfalls. This area is where our tour leader, Hywel “Taff” Roberts, was born and grew up, so he could give us some extra historical details about everything we saw. For example, the giant tree in that last picture was something that he remembered since childhood, home for birds and animals galore. It is old now, which is why several large branches have broken off.
Tomorrow the tour ends, and Diane and I will be taking the train to London, where we will spend two days before flying back to the states.

Wisconsin HS students win U.S. rocketry competition
A team of high school students from Wisconsin have won U.S. rocketry competition and will now represent this country in the international competition to be held at the Paris International Air Show in June..
The team’s victory follows months of preparation designing, building, and testing a rocket capable of meeting rigorous mission parameters set by the contest’s sponsors – the Aerospace Industries Association (AIA), National Association of Rocketry, and more than 20 industry sponsors. This year’s rules celebrated the 50th anniversary of Apollo 11 by requiring each rocket to carry three eggs in a separate capsule to symbolize the three astronauts that made the journey to the Moon and back.
The Top 101 teams, hailing from 25 states from Hawaii to New York, competed for a total of $100,000 in prize money and scholarships at the national finals – an all-day event held at Great Meadow in The Plains, Va., outside of Washington, D.C. The $100,000 prize pool will be split among the Top 10 teams, with Madison West taking home the top prize of $20,000 as U.S. champions. In addition, the top twenty-five finishers receive an invitation to participate in NASA’s Student Launch initiative to continue their exploration of rocketry with high-powered rockets and challenging mission parameters.
The growth of this competition is clearly tied directly to the boom in commercial rocketry going on worldwide.

Wales Day 6
c
c
After yesterday’s long hike on Mount Snowdon, today was planned as an easier day. First we changed locations, driving south to the village of Dolgellau.
In the morning we heard two short presentations, first about the first discovery of Wales by tourists in the 1700s, and second a more scholarly look at the place names of Wales that appear connected to Arthur. In this case the speaker, Scott Lloyd of the Royal Commission on Ancient and Historical Monuments of Wales, was focused more on what is really known, and was thus less sure about Arthur’s links to Wales than our previous expert, Gareth Roberts. Lloyd has documented the many place names (see his book, The Arthurian Place Names of Wales), but he has also documented the important detail that most started appearing after the first writings about Arthur started to appear, with most appearing several centuries after Arthur supposedly lived. This suggests that the names were chosen because of the legend, not because the man had been there.
In the afternoon some of us did a short hike halfway up the nearby mountain Cader Idris. The first picture shows the mountain at the top right, with sheep in the center, and a hawthorn tree in bloom to the left. The second picture shows the trail going uphill parallel to one of the many typical stone walls found everywhere in Wales. The land is very rocky, and to make it better for grazing farmers would clear the stones from the fields, putting them in piles to the side. Then, when the enclosure laws were passed in the early 1800s they used those stones to build the walls to define their property lines.
The third picture shows Taff and Barbara ahead of me, with Cader Idris in the distance. Shortly thereafter we stopped to lie on the soft heather to chat and admire the countryside and the grey rocky slope going up to the peak ahead of us. We then headed back down for dinner and an evening in town.

Wales Day 5
The goal today was to hike up to the top of Mount Snowdon, the highest point in Wales, as well as the island of England. Diane and I didn’t make it, but not for want of trying.
The route we took started at the trailhead of the Rhyd Ddu trail, one of the more popular routes up the mountain. The top photo to the right shows the view from the lower elevations of this trail, and gives a good sense of the beauty, barrenness, and dampness of the day. Though it never really rained on us, the sky was almost always overcast and the cloud cover sometimes came down to engulf us.
Rather than take Rhyd Ddu straight north to the top, however, our route has us head right (east) up the Clogwyn Du trail through the now inactive West Snowdon slate quarry, and then turn left (north) up the nose of a very steep ridgeline to meet up with Rhyd Ddu close to the summit. The second image on the left shows Diane standing on the trail surrounded by slate tailings from that quarry.
The next picture shows Hywel “Taff” Roberts, our leader and the owner of Wild Wales Tours, with the distant mountain floor below us. We have begun the climb up the nose of that ridgeline, with the initial section up a very steep stone staircase cut into the ground. I could not help but think of the stairs of Cirith Ungol from Tolkien’s Lord of the Rings.
The last photo was taken by Taff showing our entire crew, with the peak of Mount Snowdon hidden by clouds at the top center of the image. From left to right we have Pat, Dennis, the sisters Penny and Barbara, our second guide Haf, and then Diane and myself. The peak at the top-left is actually the start of the knife-edge ridgeline that leads to the peak. Where that ridgeline begins Clogwyn Du meets up again with Rhyd Ddu, which follows that very narrow knife-edge ridge to the summit, with 1000 foot drop-offs on either side.
When we got to Rhyd Ddu on that ridgeline Diane and I decided to head back down on Rhyd Ddu. We were now in the clouds, so going on to the peak seemed silly as we likely wouldn’t be able to see anything. Moreover, it was colder than either of us are used to or like. While Taff came down with us, everyone else continued to the peak. As I write this they have not yet returned, though I have no doubt they had a spectacular time crossing that ridge to the summit. UPDATE: The rest of the crew made the peak, but could see nothing for that entire section of hike, because of the clouds.
Not making the summit does not bother me much. I like to get to the top, but also know that we could it do another time should we decide to try. Diane and I have been doing this for a lot of years. We know our capabilities. We don’t need to prove them to others or ourselves.
Besides, the views up until then had been breath-taking, and they continued to be as good on the hike down. This was why we came, and it paid us amply in beauty every step of the way.

Wales Day 4
Today’s adventure in Wales was a pleasant seven mile hike up onto a small hill, Dinas Emrys, nestled in the pass in Snowdonia National Park that crosses from north to south Wales past Mount Snowdon. Our hotel, Sygun Fawr, can be seen in the lower left corner in the first picture on the right, which I took from the top of this hill. If you look close, you can see the window of our second floor room, looking out at the mountains.
The hike was through some of the lushest green woods I’ve ever seen, as illustrated by the second picture on the right. The trail itself was clearly very old, with stone steps and even a simple bridge made of flat stones and laid across a stream with a single larger rock in the center for support.
The hill itself is associated with Merlin in a number of ways. For example, the pool at the base of the waterfall in the third picture has been called Merlin’s Pool for centuries. Furthermore, Merlin supposedly hid a treasure in a cave somewhere on the hill, which will only be discovered by someone with golden hair and blue eyes and who will be guided to the cave by a bell ringing.
Fleeing Anglo-Saxon invaders Vortigen came to Wales and chose the hillfort as his retreat. However all efforts at building on the site failed, with workers returning daily to find collapsed masonry. Vortigern was counselled to seek the help of a young boy born of a virgin mother; a suitable boy was found named Myrddin Emrys (Merlin Ambrosius). Vortigern’s plan to kill Myrddin to appease the supernatural powers preventing him from building his fortress was scorned by Myrddin who instead explained that the fort could not stand due to a hidden pool containing two dragons. The White Dragon – he explained – of the Saxons would in time be defeated by the British Red Dragon.
The fourth pictures shows Gareth Roberts, our guide who as mentioned yesterday has been researching Welsh Arthurian place names, standing on the foundation of the ruin at Dinas Emrys’ top. To his left and slightly lower down on the hill in a gully was a second foundation and a pool from a natural spring. This spring was another reason this hilltop was a favored site for a stronghold, as it not only gave clear views both up and down the valley, was very defensible, but also had a ready supply of water. A fortress here would withstand attack for a considerable time.
Tomorrow we climb Mount Snowdon itself, The hike’s length will likely be about nine miles, and will gain 2,900 feet in elevation, somewhat comparable to many hikes in southern Arizona. The weather looks excellent, with spring temperatures at the mountain’s base.

New LRO pictures showing Beresheet impact site
The Lunar Reconnaissance Orbiter (LRO) science team yesterday released an image showing the impact site where the privately-built Israeli lunar lander Beresheet crashed onto the surface of the Moon on April 11, 2019.
“The cameras captured a dark smudge, about 10 meters wide, that indicates the point of impact,” said NASA. “The dark tone suggests a surface roughened by the hard landing, which is less reflective than a clean, smooth surface.”
The image released does not see the spacecraft but the surface evidence that an impact took place. Higher resolution images will be required to spot any surface wreckage.

Hayabusa-2 aborts close-in drop of visual marker on Ryugu
Japan’s asteroid probe Hayabusa-2 automatically aborted a planned drop of a visual markee on the asteroid Ryugu at the site where the probe created a crater in April.
Thursday’s mission was to observe the targeted area in detail and drop a marker from an altitude of 10 meters. But officials say the probe automatically suspended the operation after it descended to about 50 meters above the surface. It then headed toward its standby position of 20 kilometers above Ryugu. Hayabusa2 is designed to automatically abort its landing if it detected any irregularity. The agency is looking into the cause of the arrested descent.
Once the marker is eventually in place, they will use it for guidance during a a second touchdown to grab further samples, this time hopefully of material churned up by the explosion that created the crater.

Wales Day 3
Our travels today in Wales took us to three sites, all completely different.
First we visited Bryn Celli Ddu, a neolithic burial chamber, built about 5,000 years ago and shown in the top right photo. After following a well-defined path along the edge of two fields, we all entered this mound and stood in the chamber inside. The entrance shown in the image was aligned with the summer solstice so that the sun at sunrise would beam directly into the inner chamber.
Next, we drove to the northeast corner of the island of Anglesey to climb a flat-topped hill called Arthur’s Table. Our guide, Gareth Roberts, has been doing extensive research on the place names in Wales that appear to link directly to the legend of King Arthur. It is his contention (supported by those place names as well as research by others) that Arthur was actually a Welsh military leader, born of Roman parents (who had integrated into Welsh society) and who united the tribes to fight the Saxon invaders in the sixth century, after the Romans had abandoned the British Isles. He has found more than a hundred place names in this part of Wales named in honor of Arthur. He has also found in the written record much evidence linking Arthur to Wales and the war to resist the Saxons.
This particular hilltop has been identified by archeology as the location of a significant Welsh village from the time the Romans were conquering Great Britain. The middle right photo, taken from the top, looks east across the Menai Strait that separates Anglesey from the mainland, with the mountains of Snowdonia beyond. This strait is where the Romans crossed in their first attempt to conquer Anglesey and Wales.
Roberts’ thinks that the Round Table from the King Arthur legends was a misinterpretation by later French and British storytellers of this important Welsh hilltop village. Instead of being a table where Arthur ruled with his knights, the table was this hilltop, where that Roman invasion was first spotted during their initial invasion. Five hundred years later, when the Saxons invaded and Arthur led the resistance to them, Roberts’ believes the name was given because in some way Arthur was connected to it.
The third image shows slate cutter John Jo as he demonstrates how to split slate into the thin slate tiles that are used to cover rooftops. We watched this demonstration as part of a full tour of the National Slate Museum, nestled within the mountains on the way to Snowdonia, where for more than hundred years one of the world’s biggest slate mines mined, processed, and sold slate. Closed since 1969, the mine facility now serves as a museum. The most spectacular feature of this mine facility was the still functioning giant water wheel, more than fifty feet in diameter, that was turned by a stream of gravity-fed water at its base and was used to run all the belts that powered all the belt-driven machinery in the facility. The video of the wheel, embedded below the fold, shows the wheel as we saw it today. Unfortunately it does not include any people in it for scale, though one of the last shots shows a ladder for accessing the wheel’s top. Trust me, a person seems dwarfed by this wheel.
We then drove up over the mountain pass in Snowdonia National Park to our hotel, nestled at the base of Mount Snowdon. We shall be spending the rest of our trip hiking these mountains. The hike tomorrow will once again be led by Gareth Roberts and will show us further links between Arthur and Wales. On Sunday we will attempt to hike to the top of Mount Snowdon.

The video of the wheel, embedded below the fold, shows the wheel as we saw it today. Unfortunately it does not include any people in it for scale, though one of the last shots shows a ladder for accessing the wheel’s top. Trust me, a person seems dwarfed by this wheel.
We then drove up over the mountain pass in Snowdonia National Park to our hotel, nestled at the base of Mount Snowdon. We shall be spending the rest of our trip hiking these mountains. The hike tomorrow will once again be led by Gareth Roberts and will show us further links between Arthur and Wales. On Sunday we will attempt to hike to the top of Mount Snowdon.

Wales Day 2
Our journey through Wales continues. Today, as with yesterday, we explored the island Anglesey, which forms the northwest corner of Wales.
The day began going to Anglesey’s northwest coast to hike north to the South Stack lighthouse, as shown in the top right image. At this resolution you cannot see them, but the greyish-green rock faces rising one third to halfway up these cliff faces are covered with thousands and thousands of birds, including the guillemots, razorbills, chough, and puffins. Among them also stalks the herring gull, which is hoping to pick off an easy meal by grabbing the young offspring of the other birds.
We walked about two miles along these high dramatic cliffs to the lighthouse, which unfortunately was closed today because it had been reserved for an elementary school class trip.
We then drove to the little visited ruins of Din Lligwy (don’t ask me to explain how to pronounce it), shown in the second image to the right. These ruins are hidden behind trees on a high hill overlooking the part of the Irish Sea north of Wales and are what is left of a Welsh/Roman village. The ruins include the circular stone structures used as foundations for Welsh homes as well as the square stone wall/foundations used by the Romans. It is thus thought that after the Romans conquered Wales and before their abandonment of the British Isles the Romans intermarried with the Welsh and added their architectural designs to that used by the Welsh. The image shows the largest square foundation, with the two standing stones delineating the building’s entrance. To the left, out of frame, is a Welsh circular structure that to my eye looked exactly like a kiva that one sees in all the American Indian ruins of the southwest.
After visiting a number of other ruins, we then headed to the island’s southernmost point, to the peninsula of Ynys Llanddwyn, also called Dwynwen’s Island. It is no longer an island, because in the 1400s a giant storm, followed by several more, dumped a gigantic amount of sand along the shore, thus extending that shoreline several miles seaward and connecting the island to the mainland.
The bottom picture shows the peninsula’s distance lighthouse, and the ruins of a church (the arch) built to honor Dwynwen, who had been a Welsh princess. According to legend, she had been betrothed but fell in love with another man, who when he found out about the betrothal attacked her. This broke her heart, and she ended up running away to live unmarried on this island for the rest of her life, dedicated to helping unhappy lovers. For this she was made the patron saint for lovers by the Catholic Church.
To visit all these sites required us to cross Anglesey practically from the top to the bottom, generally traveling secondary roads. The land was a gentle rolling terrain, covered with numerous small farms whose amazingly lush and well-kept fields were devoted almost entirely to grazing sheep and cattle. The villages were all small, whose packed trim homes were either built during the 1800s or built to fit that style. Overall I got the impression that though this part of Wales might not be wealthy, its people had a strong sense of civic pride.
Tomorrow we head to Mount Snowden and the mountains. The scenery should get a bit more dramatic.

This will be a short post, as we are about to leave on our second day’s adventures.
To the right is the plane that finally got us out of the U.S. to London, where we had to transfer again to get to Dublin. Twas nice to fly on a 747, rapidly disappearing from the fleets of American airline companies. British Airways however appears to still be flying a lot of them. A super smooth flight on this magnificent plane.
Transferring planes in Heathrow was horrible, as it seems all international travel is becoming. Even though we were never leaving the terminal they still forced us to go through customs.
The second picture shows the view from the coastal village of Rhosneigr at the end of the day. We had met up with our group and had just completed a 4 mile hike along the beach. It seems there are a lot of bird watchers among us. It also seems in a way like we were back at Cannon Beach, without any crowds at all.
Time to go! More later.

Fascist scientists propose excluding 85% of solar system from human use
The tyrannical Earth moves to oppress future spacefarers: Scientists have now proposed a new fascist plan designed to exclude any human development in 85% of the entire solar system.
Great swathes of the solar system should be preserved as official “space wilderness” to protect planets, moons and other heavenly bodies from rampant mining and other forms of industrial exploitation, scientists say.
The proposal calls for more than 85% of the solar system to be placed off-limits to human development, leaving little more than an eighth for space firms to mine for precious metals, minerals and other valuable materials.
While the limit would protect pristine worlds from the worst excesses of human activity, its primary goal is to ensure that humanity avoids a catastrophic future in which all of the resources within its reach are permanently used up. [emphasis mine]
These fascists really only want power. They really have no interest in preserving anything. If their proposal was ever made law it would put control over that 85% in the hands of bureaucrats on Earth, not the people who will be living and working in space and who would also know best how to handle the situation. Also, their justification for the proposal, to prevent humans from using up all the available resources, is beyond ludicrous. We haven’t yet come close to using up Earth’s resources, even though doomsayers have been predicting that to happen repeatedly for the past century.
This story more than anything provides a window into the future political conflicts that will occur once humans finally establish space colonies. Much as the American colonies had to revolt from Great Britain’s overbearing power, colonists in space will have to do the same to get away from the same overbearing power coming from Earth.

America’s 10 largest cities drowning in debt
The coming dark age: According to a new report [pdf] from an independent government watchdog, the United States’ ten largest cities are all deep in debt, with taxpayer burdens for that debt ranging from $119K to $13K per taxpayer.
Almost all the cities on this list are and have been run by Democrats for decades, with Democratic strongholds Chicago, New York, Los Angeles, and Philadelphia holding the four top spots. Nor have the Republicans been innocent or responsible. In cities where they had some control, such as New York when Rudy Giuliani was mayor, little was done to rein in spending. Still, Democrats have held the bulk of political control in big American cities for the last century, so much of this debt comes from their policies.
The watchdog group that issued the report, Truth in Accounting, also focused on the dishonest accounting practices used by all these cities to hide their debt.
“The largest cities in the U.S. issue so-called ‘Comprehensive Annual Financial Reports,’ but most of them aren’t so comprehensive,” Bill Bergman, Truth in Accounting’s director of research, told Fox News via email.
The report questioned if cities’ annual financial reports “comprehensively track municipal accounts such as school districts, transit agencies, utility systems, etc.” Annual financial reports “for a city doesn’t present the full picture of their fiscal position, and is deceptive to the public,” the report said.
None of this is news. Politicians of all strips at every level of government have been faking their accounting for decades to allow them to spend more money than they have. The result is debt across the board, at every level of American government, with the worst debt held by our out-of-control federal government.
Are the politicians to blame? Yes, but the source of their corruption really falls on the voters, who have favored such politicians because they have been giving money away to those taxpayers. Rather than be responsible citizens, Americans for the past half century have been greedy and selfish, using their governments to get as many free handouts as possible. Or they have been willing to countenance big payouts to unions and others, sometimes for naive idealism, and sometimes because of pure laziness to pay attention to such matters.
Can the U.S. clean up this mess before the whole house of cards collapses? That remains unknown. Trump’s election hints that the voters might be willing to try, but then, Trump is no budget-cutting hawk. He believes in lots of government spending as well, from NASA to infrastructure. It remains to be seen whether the American public has begun to recognize this unsustainable situation. My sense is that they have become aware, but are still unwilling to make the hard sacrifices necessary to fix the problem. For example, the worst political offenders here remain the Democrats, and there is absolutely no indication of them losing power in the big urban cities named in this report. The debt grows, but the voters continue to support them.
Until we see a full house-cleaning in the Democratic Party, the situation is simply not going to improve.

Trump seeks $1.6 billion more for NASA, cuts money to Gateway
The Trump administration, in order to support its desire to accomplish a lunar landing by 2024, is requesting a $1.6 billion increase in NASA’s budget for fiscal year 2020. The key detail however is this:
NASA shortly thereafter published a summary of its budget amendment, which calls for nearly $1.9 billion in new funding for developing lunar landers and accelerating work on the Space Launch System and Orion. It would also go towards exploration technology development and additional science missions to the moon. That increase would be offset by cutting funding for the lunar Gateway by $321 million, reflecting the agency’s plan for only a “minimal” Gateway needed to support a 2024 landing.
In other words, in total Trump wants $1.6 billion more. The good news: He is de-emphasizing Gateway in his future plans. This might even lead to its cancellation as a project.
The bad news? He is pumping more money into SLS/Orion. However, this might not be that bad, when one considers how our bankrupt Washington government functions. Trump doesn’t have the political backing to cut SLS/Orion outright. Instead this proposal is that project’s Hail Mary pass for a touchdown. While private efforts continue to mature to develop cheaper rockets and manned capsules, SLS/Orion will have this one last chance to finally prove itself. If it finds it can’t get it done, and those private options show that they can, then Trump might finally be able to harness the political will in our dumb Congress to dump SLS/Orion.
And if SLS/Orion does succeed? The victory will likely still be a Pyrrhic one. SLS/Orion will still be too expensive and too slow to do much else but a single lunar landing, a stunt much like Apollo, with far less long term possibilities. Meanwhile, those private efforts will continue to develop. By 2024 a switch by NASA to private enterprise and competition will still make sense anyway, even if SLS/Orion gives the nation a spectacular lunar landing.
This action indicates that the Trump administration is paying attention to these matters. They are creating a situation that will put them in a strong negotiating position to get what they want, for the nation. One way or the other, we will be heading back to the Moon.
One minor detail: NASA has chosen “Artemis” as the name for its project to land on the Moon by 2020.
Bridenstine also … announce[d] that this 2024 lunar landing mission will be named Artemis, after the sister of Apollo and the Greek goddess of the moon. “I think it is very beautiful that, 50 years after Apollo, the Artemis program will carry the next man and the first woman to the moon.”
No one should be fooled by this. Apollo was a full program, with a well-thought slate of missions designed to get us to the Moon quickly. This SLS/Orion project is still an off the cuff mishmash, with only two or three flights at most, and without much of a plan behind those flights. It has been and continues to be an improvised mess.

Are Boeing and SpaceX having parachute issues with their manned capsules?
There appears to be a significant conflict between what NASA has been saying about the parachute development tests for both SpaceX’s Dragon capsule and Boeing’s Starliner capsule and what the companies have reported.
The head of NASA’s manned program, Bill Gerstenmaier, has said that both programs have had “anomalies” during their tests. Both companies have said otherwise, with both companies claiming that all their parachutes have been successful. The article looks into this, and what it finds tends to support the companies over Gerstenmaier. There have been issues, but not as terrible as implied by Gerstenmaier.
So what is going on? I suspect that Gerstenmaier is overstating these issues as part NASA’s game to slow-walk the private capsules in order to make SLS not look so bad. He would of course deny this, but that denial won’t change my suspicions, in the slightest. I’ve seen NASA’s bureaucracy play too many games in connection with getting these capsules approved for flight to be generous to Gertenmaier or NASA. I don’t trust them. I’ve seen them make dishonest accusations against SpaceX and Boeing too many times already.

Finally in Dublin
Because American Airlines cancelled our Sunday night flight to Dublin (on the way to Wales), we ended up getting here one day late. The result is that we are both exhausted, partly from two days of travel, and partly because the messed up flights has made it harder to adjust to the time change.
My impression of American Airlines drops with every flight. This time they were very disorganized in every way in dealing with the cancellation, caused because our airplane had a maintenance issue. We managed to get our new flight plus our hotel, taxi, and food vouchers quickly because we did some smart quick thinking, working as a team. However, though American told us we were now going to be on a British Airways flight and would send me an email confirmation within minutes, that confirmation never arrived, and when we got to the BA ticket counter the next day they knew nothing about us. Fortunately,. the BA ticket person was great. She called American and got our tickets issued.
I should add that we had an almost identical experience coming home from Oregon on Southwest only a little more than a week ago. Not only did Southwest keep us better informed, they also were able to find another plane and crew and got us out the same night, though six hours late. Moreover, Southwest gave everyone on the flight a $100 voucher, unasked, as an apology for the delay. American meanwhile offered us nothing as recompense. And their food vouchers were pitiful, failing to cover the cost of any meal at the airport.
I will try to post more tonight, but likely I won’t get much done until tomorrow.

The floor of Marineris Valles
Click for the full image.
To the right is small section cropped out of an image, taken by the high resolution camera of Mars Reconnaissance Orbiter (MRO) on March 30, 2019, of one very tiny area of the floor of the 2,500 mile long Marineris Valles, the biggest known canyon in the solar system.
Below this on the right is a larger section of the full image, with the white box showing the part covered by the top photograph. The general flow direction is to the east.
The photograph, uncaptioned, is titled “Terminus of Pitted Materials Emanating from Oudemans Crater.” Oudemans Crater is about 55 miles across and is located near the head of Marineris Valles to the east of the giant volcanic region dubbed the Tharsis Bulge. The meteorite that caused this crater is estimated to have been a little less than 3 miles in diameter. It is believed by some scientists that the impact heated up subsurface carbon dioxide permafrost which then explosively flooded down the Valles Marineris into the Northern Plains of Mars, pushing a lot of pulverized debris in front of it..
Instead of liquid water, what is stored underground on Mars is liquid CO2 and when a collapse occurs, this boils almost instantly and explosively to CO2 vapour, blasting the rock and regolith to dust, except for the most resistant fragments such as igneous rocks. The rest of the regolith is composed of dust and gravel, weakly cemented by water ice. On Mars, water is not a fluid, but behaves as a mineral in most situations. Grains of ice would be tumbled along in the cryogenic flows, and transported as passive solids just like quartz grains are transported as sand by rivers on Earth.
This theory, if correct, would eliminate the need for liquid water on the surface, and would explain many of the planet’s geological surface features.
The overview thumbnail to the left shows the location of both Oudemans Crater and this MRO image, indicated by the very tiny blue rectangle near the thumbnail’s center..
The “pitted materials” in the image’s title refers to that flowing avalanche of pulverized ice, rock, and dust, shown in the picture by the curved terraced cliffs descending to the east. This is where this material settled as it flowed eastward, pushed by that explosive CO2 flood.
You can see another example of this eastward flow in another MRO image taken just to the west. The canyon floor is pitted, confused, and rough, but there is an obvious flow trend to the east.
In fact, much of the floor of Marineris Valles that has been photographed at high resolution is similarly rugged. It will be a challenge to explore this place, especially because we have only imaged a small percentage at high resolution. There is much there that remains unseen and unknown.

This theory, if correct, would eliminate the need for liquid water on the surface, and would explain many of the planet’s geological surface features.
The overview thumbnail to the left shows the location of both Oudemans Crater and this MRO image, indicated by the very tiny blue rectangle near the thumbnail’s center..
The “pitted materials” in the image’s title refers to that flowing avalanche of pulverized ice, rock, and dust, shown in the picture by the curved terraced cliffs descending to the east. This is where this material settled as it flowed eastward, pushed by that explosive CO2 flood.
You can see another example of this eastward flow in another MRO image taken just to the west. The canyon floor is pitted, confused, and rough, but there is an obvious flow trend to the east.
In fact, much of the floor of Marineris Valles that has been photographed at high resolution is similarly rugged. It will be a challenge to explore this place, especially because we have only imaged a small percentage at high resolution. There is much there that remains unseen and unknown.
Off to Wales for two weeks
Today Diane and I are off for a two week vacation hiking and sightseeing in Wales, beginning with a day in Dublin and finishing with two days in London. During that time I will continue to post, but expect my posts to show up at very odd hours, as I settle into the British time zone, five hours ahead of New York.
Along the way I should also post, as I usually do, some commentary and pictures about our trip and my impressions of this insistently different part of Great Britain. The description of the tour itself can be found here.
For me this trip will be a very different experience, in that in all my other travels I always made all the arrangements, in order to save money. This time we decided to splurge and let someone else do that work. Should be fun, and most interesting.

Yutu-2 travels more than 600 feet during its fifth lunar day on the Moon
The Chinese press today revealed that during its fifth lunar day on the Moon’s far side China’s lunar rover Yutu-2 traveled about 623 feet.
Where exactly it went, and what it learned, they did not reveal. We will have to wait for Lunar Reconnaissance Orbiter images to learn the rover’s route.
They have now put both Yutu-2 and the lander Chang’e-4 into sleep mode for the long lunar night.

Virgin Galactic to move flight operations to New Mexico
Capitalism in space: As promised more than a decade ago, Virgin Galactic yesterday announced that is finally going to move its SpaceShipTwo flight operations from Mohave to the Spaceport America facility in New Mexico this summer.
This fulfills Virgin’s original agreement with New Mexico, where the company agreed to base its commercial operations there if the state spent money to build the spaceport. The move is beginning now, but will mostly occur in the summer. It suggests the company might finally be getting ready to at last begin commercial tourist flights, only a decade-plus later than originally promised.
As is usual, Richard Branson made this a big public relations event. And as is usual, numerous press outlets have swooned over it. I remain very skeptical.
